Potential origins and transport routes of ceramide species around the body. This is a summary of known transport routes and packaging systems of ceramide species as determined from the current literature. Question marks and broken line arrows are suggestive of new routes and transport routes mechanisms that have recently been proposed or published. ApoB, Apolipoprotein protein; EV, Extracellular vesicle; LDL, low density lipoprotein; VLDL, very low-density lipoprotein; HDL, high density lipoprotein.
